Abstract

The present invention is an image signal processing circuit, comprising; a first memory part; a second memory part; and a control circuit which controls the first memory part and the second memory part, wherein the image signal processing circuit is constituted so that image signals outputted from one of the first memory part and the second memory part are inputted into the other of the first memory part and second memory part; and wherein the control circuit is a circuit which controls the first memory part so that image signals are outputted inverse order from the first memory part to inputted order into the first memory part, and controls the second memory part so that image signals are outputted inverse order of lines composed of image signals from the second memory part to inputted order of lines composed of image signals into the second memory part.
